DRYING-CYLINDER.

SPECIFICATION forming part of Letters Patent No. 676,684, dated June 18,1901. Application filed September 10, 1900. Serial No. 29,604.memorial.)

T0 aZZ whom it may concern:

Be it known that I, BARTHoLoMEw OR- MEROD, sizer, a subject of the Queenof Great Britain, residing at 2 Swiss street, Accrington, county ofLancaster, England, have invented certain new and useful Improvements inDrying-Cylinders, of which the following is a specification.

This invention relates to drying-cylinders heated by steam used insizing or slashing machines for drying yarn after it has been submittedto the sizing process and also to similar drying-cylinders used forother purposes. Hitherto steam has been allowed to enter the cylinderthrough holes in the tubular shaft of the drying-cylinder. Inconsequence of the considerable area between the place of admittance ofsteam and the dryingsurface of the cylinder a waste of steam takes placein eifecting the heating of the cylinder to the required degree. In myinvention, which is designed to remedy this evil, I tap the holes in theshaft for the inlet of steam and conduct therefrom a pipe or pipes,which may be elbow-join ted or otherwise formed, so that the steam maybe conveyed from the shaft to circular tubes or hollow bands perforatedat suitable distances apart and adjacent to the drying-surface of thecylinder, whereby small jets of steam issuing from the circular bandsplay direct upon the dryingsurface of the cylinder. The circularperforated hollow bands are placed at suitable distances apart to bringabout an equal distribution of heat over the drying-surface of thecylinder, and the steam is put to its fullest and best use. At presentthe steam-inlet holes made in the shaft are usually three in number, andaccording to my invention I tap each of these and conveyseparate pipestherefrom-to the perforated circular and tubular bands to any desiredpart of the drying-cylinder. I do not confine myself, however, to theemployment of three separate pipes to convey steam to the circularbands, as one or two larger pipes may be employed and branch pipesextend from these to the said bands. The circular hollow perforatedbands are preferably carried over the cylinder-bars and clipped orotherwise secured thereto. The

proximity of the circular bands to the drying or heating surface of thecylinder may be varied as may be found most convenient for effecting theproper drying of the material carried over it, and their distances apartand from the sides of the cylinder may be such as to best effect theproper drying of the material or articles passing over thecylindersurface.

In the accompanying drawings, Figure 1 is a side elevation, partly insection, of a steamheated drying-cylinder; and Fig. 2, a crosssection ofthe same, with my invention applied for economizing steam and equalizingthe distribution of heat over the cylindersurface. Figs. 3 and 4 aredetail views of the clips for supporting the hollow bands.

A is the tubular shaft of the drying-cylinder, provided with the usualstuffing-box and gland and inlet-pipe for the supply of steam to thecylinder. The three steam-inlet holes usually made in the tubular shaftA are according to my invention tapped to receive pipes, such as B, C,and D, which convey the steam from thence to three circular hollow bandsE, F, and G, which are perforated at suitable distances apart, as shown,so that jets of steam may play direct upon the dry-- ing-surface. Thecircular bands or tubes are preferably carried over the cylinder-bars Hand are clipped or otherwise secured thereto by a series of clips, eachconsisting of a bar 1, provided at one end with a hook 2 for em bracingthe bands and adjustably connected by means of the nut 3 and bolt 4: to'the hanger 5, provided at one end with a hook 6 to permit of mountingupon the cylinder-bars. These clips are disposed at any desirabledistance from the surface of the cylinder and from each other and thesides of the cylinder, so that the absorption and distribution ofcaloric derived from the steam by the dryingsurface may be as completeas is practically possible.

Instead of three. perforated circular and tubular bands two or four maybe used; but I prefer three, as being most suitable.

Having now particularly described and ascertained the nature of myinvention and in what manner the same is to be performed, I declare thatwhat I claim is-- 1. In a drying-cylinder,cylinder-bars secured therein,perforated hollow bands arranged in said cylinder and connected to said3. In a drying-cylinder, a shaft connected thereto, cylinder-barssecured Within said cylinder, perforated hollow bands arranged in saidcylinder in close proximity to the drying-surface thereof, and pipesconnected to said shaft and bands for supplying a drying medium to thelatter.

4. In a drying-cylinder, circular perforated hollow bands suitablysecured therein, and means connected to the said bands for supplying adrying medium thereto.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

BARTHOLOMEVV ORMEROD.
